The Runaways.

Peter runs away from home after breaking a window. He seeks shelter in the hayloft of a church barn and meets the minister’s son Georgie and the family's ward Carmen. The trio get involved in a bit of mischief making which takes a hazardous turn when they start for a ride down a grade on a handcar and find themselves tearing wildly toward an onrushing express train. Georgie saves the day and chagrined Peter returns home.
